Title: Bias circuit to be used together with memory cell in brake-make memory
Inventor: SUCHIYUAATO TEI OOBINEN
IPC: G11C11/419
Filed: 1990-07-13
Abstract: PURPOSE: To make it possible to obtain a bias circuit for intermittent memory for compensating leak currents without consuming electric power by continuously biasing bit lines during the time of a reading out operation in such a manner that first and second P channel transistors compensate the leakage without consuming electric power. CONSTITUTION: The bias circuit is composed of a cross coupled half latch circuit 32 which compensates the leakage of the currents without consuming electric power, continuously biases the bit lines 12 and 14 in the memory array and consists of an N channel MOS bias transistor M1 and a pair of P channel MOS transistors M2 and M3. The latch transistors M2 , M3 act to hold the states of the bit lines 12 and 14 and, further, hinder the dispersion of the electric power by turning off the direct route between power source potential VCC and the ground. As a result, the improved bias circuit capable of compensating the leakage of the bit liens without consuming the electric power is obtd.

IPC: G10L15/06
Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To quickly prepare a classification tree for classifying patterns having featured values expressed by plural dimensions. SOLUTION: A hierarchical segmentation pre-processing part 102 hierarchically segments each dimension of a featured value used for classifying a learning pattern 101, and decides the threshold value of each dimension, and prepares a hierarchized learning pattern 103 indicating to which segment of each segmented dimension each featured value of the learning pattern 101 belongs. A development variable discriminating part 105 selects a dimension (variable) whose classification efficiency is the highest in each node in a classification tree. A classification tree preparing part 104 prepares a classification tree bases on the hierarchized learning pattern 103, the dimension obtained by the development variable discriminating part 105, and a threshold value set for the dimension.

Title: Instrument for detecting roll slip of steel strip rolling mill
Inventor: ITO KOJI
IPC: B21B38/00
Filed: 1996-07-17
Abstract: PROBLEM TO BE SOLVED: To restrain and prevent the occurrence of slippage between rolls by providing a detecting means for detecting the slippage between the rolls with a pulse counter detected by a pulse detecting means. SOLUTION: When the pulse counter 6 count-integrates the pulse outputted from a work roll fitting PGW 5 and inputs a backup roll pulse PGB 2, the count value PWI is outputted to an arithmetic circuit 9 and at the same time, the count value is reset and the count integration of the PWI of the PGW outputted pulse is again repeatedly executed from zero. The arithmetic circuit 9 outputs the slippage ratio R between the rolls to a comparator 10 and a comparator 13. The comparator 10 compares an allowable slippage ratio R1 and the slippage ratio R between the rolls outputted from the arithmetic circuit 9, and when the R is larger than the allowable ratio R1, the allowable excessing signal is outputted to an alarm generator 12 to call the countermeasure for reducing the slippage between the rolls.
